I have a question and I think it likely a stupid one. I have ordered a pair of Dan Clark Aeon headphones... Currently it'll only come with a 3.5mm cable so I will only be able to run Unbalanced, at a max power of 375mw @ 32 Ohms. The Noire are rated as a 13 Impedance headphone, does that mean the power of the Gryphon will be greater than the 375mw power stated in the manual, or the same. Sorry, slowly getting there with impedance, clearly I am not quite there yet
What is the specified sensitivity ?
I can give you some calculation figures if you tell the sensitivity, but being a planar magnetic I have to assume it's likely in the 80-90dB/mW range.
At first glance, I would say those headphones seem very hard to drive and will most certainly require a balanced cable for a loud/very loud volume.
At the end of day it depends how loud you like to listen, cause in practice achieving a moderate SPL doesn't require much power at all, but the higher
you go in loudness, the required power to drive them will increase exponentially.
I believe it is more likely a problem with the plugs than the Gryphon’s jack.
I have had a couple of cables that had this issue. I recently bought some nicer quality cables and none of them exhibit this issue. I guess they have better quality plugs that have proper specs.
This is interesting. I read this 4.4mm jack problem many times in this thread, but never experienced it myself.
The cables I have used are both the ones that came with particular headphones or IEMs (so good quality ones), but also ones from Aliexpress that work equally good.
As
@LORDROOTMAN mentioned, the connector needs extra force to be pushed all the way in, there is more resistance for the last 2mm or so.
Maybe there are inconsistencies in regard to the connector in the Gryphon, some being better (in terms of tolerances) than others.
